[0002] Automobile shock absorber is the key component of automobile suspension system, and its main role is to reduce the vibration and impact caused by road conditions, acceleration, deceleration or turning during vehicle driving. Traditional shock absorber is mostly based on hydraulic principle, but with the improvement of automobile performance requirements, single type shock absorber has been difficult to meet the demand. Composite automobile shock absorber emerges as the times require, which integrates multiple technologies, such as hydraulic-gas pressure composite, hydraulic part generates damping force through oil and piston movement, and gas pressure part provides additional support and shock absorption by using compressibility of gas; or hydraulic-electromagnetic composite, electromagnetic part adjusts damping characteristics by changing the viscosity of magnetorheological fluid with electromagnetic coil. Composite shock absorber can adapt to various road conditions, has strong adjustability, can reduce vehicle part wear, improve driving stability and comfort, and can also realize vehicle height adjustment and other functions, so it has a wide application in modern automobiles.

[0003] Traditional automobile shock absorber is mainly based on hydraulic use. It is generally composed of shock absorber cylinder, piston, oil and the like. When the vehicle driving encounters vibration, such as passing through bumpy road, accelerating or braking, the piston moves up and down in the shock absorber cylinder, and the oil flows in the shock absorber cylinder through the valve and oil way on the piston. Since the oil flowing through the small hole or narrow channel will generate damping force, this damping force can prevent the rapid movement of the piston, thereby effectively reducing the vibration and impact of the vehicle body, providing a relatively comfortable experience for the driver and passengers, and also helping to protect other parts of the vehicle from excessive vibration damage.
